It is important to follow the recommended dosage and consult with a healthcare professional before beginning any zinc supplementation regimen.

Zinc and Cold Prevention

Zinc Lozenges for Cold Relief

Zinc lozenges are a popular remedy for reducing the duration and severity of cold symptoms. These lozenges typically contain zinc acetate or zinc gluconate and are dissolved slowly in the mouth. The zinc is thought to have antiviral properties, which may help inhibit the replication of cold viruses in the throat.

Effectiveness of Zinc for Preventing Colds

While the effectiveness of zinc lozenges for preventing colds is still a topic of debate, some studies have suggested that they can be helpful. Zinc lozenges may be more effective when taken within 24 hours of experiencing cold symptoms. However, it is important to note that more research is needed to confirm their efficacy.

Proper Use of Zinc Lozenges

When using zinc lozenges, it is important to follow the instructions provided by the manufacturer. It is generally recommended to allow the lozenge to dissolve slowly in the mouth, avoiding chewing or swallowing it whole. It is also advisable to avoid taking zinc lozenges for an extended period of time, as excessive zinc intake can cause adverse effects.

Zinc in Immune System Function
